Abstract:
A heddle frame stave for heddle frames includes a light metal hollow construction having, at least on one side wall, and preferably on opposing side walls, a flat groove-shaped recess. A flat steel strip is adhesively secured in the recess, the strip having a thickness of less than half the side wall thickness and covering preferably at least 60% of the surface of the side wall of the hollow stave. Vibration dampening of the heddle frame stave is thereby achieved, so that the sound produced due to vibrations and the noise development associated therewith, will be reduced considerably especially for fast running weaving machines.
Abstract:
The connecting part for electrical warp stop motions on weaving machines has two rectangular housing shells (2,3) pressed against each other at their open sides by means of a threaded pin (10) screwed into the first housing shell (2). The screw-head of the threaded pin is in the shape of a knob (11) and presses against the second housing shell (3). In the longitudinal sides (4,6) of both housing shells (2,3) are supporting slots (9) at equal distances to take up the contact bars. On the interior base (12,15) of each housing shell (2,3) is a strip (13,16) of elastic material and on each strip a contact foil (14,17) for conducting electricity to all the contact bars, the narrow edges of which have perfect contact with the contact foils, even at varying height resulting from deviations in manufacture, due to the elastic material under them. A plug pin (18), in the second housing shell (3) is in direct electrical contact to the contact foil (17) in this housing shell and a further plug pin (19) is electrically connected to the contact foil (14) in the first housing shell (2) by means of a rod (23) on the exterior of the longitudinal side of the second housing shell and by means of the screw-head (11) and the threaded pin (10).
